LONDON (Reuters) - Ruthless Arsenal threw down the gauntlet in the Premier League title race with a 5-0 thrashing of London rivals Chelsea to roar three points clear at the top of the table on Tuesday.

Any remaining doubts about Arsenal's staying power were answered emphatically as Leandro Trossard gave them an early lead before Ben White and Kai Havertz scored two each in a dazzling spell after the break to sweep aside a dazed Chelsea.
